Detailed explanation-1: -Which ecosystem would scientists consider to be the most stable? A savanna that retains the same number of species even when a drought occurs. Sometimes ecosystems change. These changes can be natural or human caused.
Detailed explanation-2: -Over time, the succession occurs in a series of plant stages, which leads to a stable final community, which is very similar to the plant community, which originally existed in the ecosystem. This final stable plant community is called a climax community.
Detailed explanation-3: -When something is in equilibrium, it’s in balance. In the real world of ecosystems, nothing is ever perfectly balanced. So an ecosystem in equilibrium is said to be in a relatively stable state. This means that the populations of various animals in the ecosystem are generally staying within a similar range.
